Python Program to Read a Random Line from a File

December 6, 2023December 5, 2023 by Vikram Chiluka

Files in Python:

One of the most important subjects for programmers and automation testers is Python file handling (also known as File I/O). It is necessary to work with files in order to write to or read data from them.

Also, if you didn’t know, I/O operations are the most expensive processes where a programme can go wrong. As a result, you must use extreme caution while implementing file processing for reporting or any other reason. Optimizing a single file action can help in the creation of a high-performing application or a reliable automated software testing solution.

Consider the following scenario: you’re planning to construct a large Python project with a large number of workflows. Then it’s unavoidable that you don’t make a log file. You’ll also be handling the log file’s read and write activities. Debugging huge applications with log files is a terrific way to go. It’s usually better to consider a scalable design from the start, as you won’t be sorry later if you didn’t.

Given a file, the task is to read a random line from the given File in Python

Program to Read a Random Line from a File in Python

Below is the full approach for reading a random line from the given File in Python

Approach:

Import random module using the import keyword
Make a single variable to store the path of the file. This is a constant value. This value must be replaced with the file path from your own system in the example below.
Open the file in read-only mode. In this case, we’re simply reading the contents of the file.
Get all the lines of the file using the read(), splitlines() functions and store it in a variable.
Print a random line from the given file using the random.choice() function by passing the above lines as an argument to it.
The Exit of Program.

Below is the implementation:

# Import random module using the import keyword
import random
# Make a single variable to store the path of the file. This is a constant value.
# This value must be replaced with the file path from your own system in the example below.
givenFilename = "samplefile.txt"
# Open the file in read-only mode. In this case, we're simply reading the contents of the file.
with open(givenFilename, 'r') as givenfilecontent:
    # Get all the lines of the file using the read(), splitlines() functions and 
    # Store it in a variable
    file_lines = givenfilecontent.read().splitlines()
    # Print a random line from the given file using the random.choice() function
    # by passing the above lines as an argument to it
    print(random.choice(file_lines))

Output:

btechgeeks

File Content:

hello
thisis 
btechgeeks
welcomeall

Explanation:

The file path is stored in the variable ‘file name.’ Change the value of this variable to the path of your own file.
Dragging and dropping a file onto the terminal will show its path. The code will not run unless you change the value of this variable.
The file will be opened in reading mode. Use the open() function to open a file. The path to the file is the method’s first parameter, and the mode to open the file is the method’s second parameter.
When we open the file, we use the character ‘r’ to signify read-mode.
We use random.choice() method to select random line from list of lines.

Python Program for Reading Last N Lines of a File

December 6, 2023December 5, 2023 by Vikram Chiluka

Files in Python:

Python file handling is a way of saving program output to a file or reading data from a file. File handling is a crucial concept in the programming world. File management is used in almost every form of project. Assume you are constructing an inventory management system. You have data in the inventory management system related to sales and purchases, thus you must save that data somewhere. Using Python’s file management, you can save that data to a file. You must be given data in the form of a comma-separated file or a Microsoft Excel file if you wish to conduct data analysis. Using file handling, you can read data from a file and write output back into it.

Give the N value and file the task is to read the last n lines of the file in Python.

Program for Reading Last N Lines of a File in Python

Using For loop (Static Input)
Using For loop (User Input)

Method #1: Using For loop (Static Input)

The concept behind this technique is to utilize a negative iterator with the readlines() function to read all of the lines requested by the user from the end of the file.

Approach:

Make a single variable to store the path of the file. This is a constant value. This value must be replaced with the file path from your own system in the example below.
Give the n value as static input and store it in a variable.
Open the file in read-only mode. In this case, we’re simply reading the contents of the file.
Get all the lines of the file using the readlines() function and store it in a variable.
Iterate in the above lines list using the for loop to get the last n lines of a file using the negative indexing.
Print the last n lines of a given file.
The Exit of Program.

Below is the implementation:

# Make a single variable to store the path of the file. This is a constant value.
# This value must be replaced with the file path from your own system in the example below.
givenFilename = "samplefile.txt"
# Give the n value static input and store it in a variable.
gvn_n_val = 2
# Open the file in read-only mode. In this case, we're simply reading the contents of the file.
with open(givenFilename, 'r') as givenfilecontent: 
    # Get the lines of the file using the readlines() function
    lines_lst= givenfilecontent.readlines()
    print("The last",gvn_n_val,"lines of a given file are:")
    # Iterate in the above lines list using the for loop to get the last
    # n lines of a file using the negative indexing.
    for fline in (lines_lst[-gvn_n_val:]):
        # Print the last n lines of a given file.
        print(fline, end ='')

Output:

The last 2 lines of a given file are:

Method #2: Using For loop (User Input)

Approach:

Make a single variable to store the path of the file. This is a constant value. This value must be replaced with the file path from your own system in the example below.
Give the n value as user input using the int(input()) function and store it in a variable.
Open the file in read-only mode. In this case, we’re simply reading the contents of the file.
Get all the lines of the file using the readlines() function and store it in a variable.
Iterate in the above lines list using the for loop to get the last n lines of a file using the negative indexing.
Print the last n lines of a given file.
The Exit of Program.

Below is the implementation:

# Make a single variable to store the path of the file. This is a constant value.
# This value must be replaced with the file path from your own system in the example below.
givenFilename = "samplefile.txt"
# Give the n value user input using the int(input()) function and store it in a variable.
gvn_n_val = int(input("Enter some random number = "))
# Open the file in read-only mode. In this case, we're simply reading the contents of the file.
with open(givenFilename, 'r') as givenfilecontent: 
    # Get all the lines of the file using the readlines() function
    lines_lst= givenfilecontent.readlines()
    print("The last",gvn_n_val,"lines of a given file are:")
    # Iterate in the above lines list using the for loop to get the last
    # n lines of a file using the negative indexing.
    for fline in (lines_lst[-gvn_n_val:]):
        # Print the last n lines of a given file.
        print(fline, end ='')

Output:

Enter some random number = 3 
The last 3 lines of a given file are:

Approach:

import the Counter from the collections module using the import keyword.
Make a single variable to store the path of the file. This is a constant value. This value must be replaced with the file path from your own system in the example below.
Take an empty list to store all the words.
Open the file in read-only mode. In this case, we’re simply reading the contents of the file.
Iterate through the lines of the file using the For loop.
Split the words of the line using the split() function and store them in a variable(it is of type list).
Loop in the above list using another Nested For loop.
Add the words to the list using the append() function.
Get the frequency of all the words using the Counter() function and store it in a variable(of type dictionary).
Take a variable to store maximum frequency and initialize its value to 0.
Traverse in the frequency dictionary using the For loop
Check if the frequency of the word is greater than maximumfreq using the if conditional statement
If it is true then set maximumfreq to the corresponding value of the key.
Take a variable to store the maximum frequency key.
Print the maximum frequency element.

Below is the implementation:

# import the Counter from collections module using the import keyword
from collections import Counter
# Make a single variable to store the path of the file. This is a constant value.
# This value must be replaced with the file path from your own system in the example below.
givenFilename = "samplefile.txt"
# Take a empty list to store all the words
l = []
# Open the file in read-only mode. In this case, we're simply reading the contents of the file.
with open(givenFilename, 'r') as givenfilecontent:
    # Iterate through the lines of the file using the For loop.
    print('The words in the given file : ')
    for gvnfileline in givenfilecontent:
      # Split the words of the line using the split() function and store them in a variable(it is of type list).
        gvnfilewords = gvnfileline.split()
        # Loop in the above list using another Nested For loop
        for words in gvnfilewords:
          # Add the words to the list using the append() function.
            l.append(words)
# Get frequency of all the words using the Counter() function and store it in a variable(of type dictionary)
freqword = Counter(l)
# Take a variable to store maximum frequency
maximumfreq = 0
# Traverse in the frequency dictionary using the For loop
for i in freqword:
    # Check if the frequency of the word is greater than maximumfreq using the if conditional statement
    if(freqword[i] > maximumfreq):
        # If it is true then set maximumfreq to the corresponding value of the key
        maximumfreq = freqword[i]
        # Take a variable to store the maximum frequency key
        maxele = i
# Print the maximum frequency element
print('The Maximum Frequency element in the given Text File {', maxele, '}')

Output:

The words in the given file : 
The Maximum Frequency element in the given Text File { btechgeeks }

Explanation:

The file path is stored in the variable ‘file name.’ Change the value of this variable to the path of your own file.
Dragging and dropping a file onto the terminal will show its path. The code will not run unless you change the value of this variable.
The file will be opened in reading mode. Use the open() function to open a file. The path to the file is the method’s first parameter, and the mode to open the file is the method’s second parameter.
When we open the file, we use the character ‘r’ to signify read-mode.
The split() method separates all of the words in the given file.
We add all the words to the list.
We apply the Counter() function to get the frequency of all the words of the given text file.

file = open(givenFilename,"r")
print("The lines having more than 25 characters are:")
# Iterate in the lines of the file using the for loop
for lines in file:
    # Calculate the length of the line using the len() function and store it in a variable.
    line_len=len(lines)
    # Check if the length of the line is greater than 25 using the if conditional statement
    if line_len>25:
        # If it is true, then print that respective line.
        print(lines)

Output:

The lines having more than 25 characters are:

hello this is Btechgeeks.welcome all

Explanation:

The file path is stored in the variable ‘file name.’ Change the value of this variable to the path of your own file.
Dragging and dropping a file onto the terminal will show its path. The code will not run unless you change the value of this variable.
The file will be opened in reading mode. Use the open() function to open a file. The path to the file is the method’s first parameter, and the mode to open the file is the method’s second parameter.
When we open the file, we use the character ‘r’ to signify read-mode.
We traverse through the lines of the file using For loop and check the length of the corresponding line using the len() function.
We print the lines which are having length greater than 25.

Python Program to Write 1 to 100 in a Text File

December 4, 2023December 3, 2023 by Vikram Chiluka

Files in Python:

Given a file, the task is to write 1 to 100 numbers into a given file in Python.

Program to Write 1 to 100 in a Text File in Python

Below is the full approach for writing 1 to 100 numbers into a given file in Python.

Approach:

Make a single variable to store the path of the file. This is a constant value. This value must be replaced with the file path from your own system in the example below.
Open the file in write mode. In this case, we’re writing the contents into the file.
Iterate from 1 to 100 using the for loop.
Convert the iterator value into a string using the str() function and write it into the file using the write() function.
The Exit of Program.

Below is the implementation:

# Make a single variable to store the path of the file. This is a constant value.
# This value must be replaced with the file path from your own system in the example below.
givenFilename = "samplefile.txt"
# Open the file in write mode. In this case, we're writing the contents into the file.
with open(givenFilename, 'w') as givenfilecontent:
    # Iterate from 1 to 100 using the for loop
    for itr in range(1,101):
        # Convert the iterator value into a string using the str() function and write it into
        # the file using the write() function
        givenfilecontent.write(str(itr) + "\t")

Output:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 
35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 
65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 
95 96 97 98 99 100

The file path is stored in the variable ‘file name.’ Change the value of this variable to the path of your own file.
Dragging and dropping a file onto the terminal will show its path. The code will not run unless you change the value of this variable.
The file will be opened in writing mode. Use the open() function to open a file. The path to the file is the method’s first parameter, and the mode to open the file is the method’s second parameter.
When we open the file, we use the character ‘w’ to signify write-mode.
We write the data to file using the write() function.
